The team behind SoMa’s flashy 25 Lusk — Matthew Dolan and Chad Bourdon — are working on a second restaurant.

The new project is planned for the top floor of the Westfield San Francisco Centre, under the dome between M.Y. China and Straits, near the top of the escalator.

The 25 Lusk guys are staying largely mum on what they have planned, especially since any prospective opening is at least a year away. But the space — which is about 5,000 square feet — would house a concept that is decidedly more casual than 25 Lusk, with the idea to make it lunch-friendly. Bourdon also teases that there will probably be a significant technology component, if things go to plan.

Cass Calder Smith, who designed 25 Lusk to acclaim in the architecture community, is rumored to be involved in this spinoff’s design as well.

Stay tuned for more details on the project in the coming weeks and months.
